Help with fixing Wi-Fi

I have reached my wit's end trying to resolve my problems, so I'm posting here for ideas on fixing this, any input is appreciated!
When this started I was on stock, rooted, ICS 4.0.3 and had been for months. My wife has a nexus s with the same config and hers works fine.
Last week, my daughters sidekick 4G stopped having wi-fi internet connectivity. I turned her wi-fi off, then back on and it was fine and has been ever since. Later that night, my nexus did the same thing, the same procedure resolved it. Ever since then, my wi-fi will only work for 1-5 minutes after turning the wi-fi on. This is the only thing I can think of that changed that could have caused this. This was the first night we connected her sidekick to wi-fi.
The wifi symbol is up there, it'll be blue for up to half an hour, but won't have internet connectivity for long. One thing I noticed pretty quickly was that even though the grey wi-fi symbol is there, I can't access the router settings at 192.168.1.1 from the phone. I thought the grey wifi symbol still indicated I was connected to the router still, but it's not working. Each time this happens, I can turn wi-fi off, back on immediately and it'll work for 1-5 minutes. It appears that the more I constantly use it after turning it back on, it seems to maintain connectivity longer.
Last weekend, just after these issues started, I visited my sister and my phone operated on her wi-fi all weekend just fine.
When I came back home, my problems started immediately.
Here's what I've tried in pretty much the order I tried them:
I started by uninstalling avast, facebook, and autostarts
selected "Forget network" in access points screen and reconnected
Factory reset
Wipe dalvik cache & fix permissions
see if it worked without sim card in (it didn't)
flash GB broadcom driver
Switched router channel from 6 to 1
flash stock 2.3.6 (wi-fi problems still present)
flash OTA ICS (still had problems)
flash stock 2.3.6
flash OTA ICS
re-root
Flash PixelROM 1.60 LiteTouch
factory reset router (No wifi problems on using open network and default SSID for 30 minutes!)
resetup WPA Personal security and rename SSID same as before
Worked for another 15 minutes or so after this
flashed stock 2.3.6
flashed OTA ICS
re-rooted
Restored nandroid backup - quit working after this step
Factory reset router - worked for about 15 minutes, I decided I was ok so I setup security and SSID as before, then it quit working again
flashed PixelRom 1.60 LiteTouch
flashed stock 2.3.6
Flashed OTA ICS - THIS time I did not restore my google backups from the cloud, fearing that this was somehow restoring something that was causing me problems. It did not help.
Changed SSID on my router and reconnected phone
I have spent countless hours trying to fix this. I don't believe it's the hardware because the router factory reset seems to help quite a bit, works fine on unencrypted default router settings, and it worked on my sister's wi-fi.
I have nmap and wireshark and have a basic working knowledge of them. I have adb setup and usable on my computer. I also have dd-wrt installed on my router and have for years. Is there any kind of IP or hardware logging I could perform with these tools to help figure out what's going on??? ANY help is GREATLY appreciated!!

Well i'm no expert with any of this, but it sounds more like a router issue.. If both your sidekick and nexus have the same characteristics of failing wifi, it cant be the devices..
If you've already reset your router and it does the same exact thing, maybe it is something wrong with the router itself. You said it connected fine at your sisters house, so it cant be any hardware within the phone.. The only thing I could think of is maybe try a different router in your house to see if it works? If that helps get rid of the connectivity issue, then you can just get a new router and be happy with the wifis

I don't think a *hardware* problem with the router would only affect 1 device connecting to it wirelessly. I would think that kind of issue would affect all devices on the network.
Which makes me wonder if there's a setting on the router that may be causing it somehow, or some combination of packets might somehow cause the router to block my phone.
But again, I'm open to ideas here and I appreciate your input. I think getting another router will be my next step if I don't hear anything better by the time I get my next paycheck.

Ohh, I thought you had said that both the sidekick and nexus were having problems connecting. My bad.
But yeah have you changed any settings on it lately? Or messed with anything related to the router? Some setting may be kicking your device off after 5 mins, maybe some frequency setting or something dumb like that, I have no clue.
I know how it feels to have funky wifi, so I was only trying to help. good luck

Have you removed DD-WRT from your Wireless Router and back to stock OS? I had a Linksys router with DD-WRT and after about 3 years it started working so weird it became useless with any device. Had to buy a new one.
BTW, are other devices connecting fine to this router?
As swamp goblin stated, I would try with a new router.

It sounds like an issue on your router (or AP) with mixed client settings. I have had this issue with an old Netgear AP.
Try forcing "WPA2 with AES only" if all clients support it, otherwise force "WPA with TKIP only". If you have mixed B/G/N devices, force the fastest mode that all devices support. I use "G only".
Then remove and re-add the router on all your devices.
Also check for router firmware updates, and if you use DD-WRT firmware, find the Wiki page for your model and revision and use the suggested build there. The DD-WRT database they have is a mess and should not be used!

I haven't changed any settings, until this problem began, which makes this even more maddening. I appreciate your input regardless

I haven't removed it. I thought I had a model that couldn't go back to stock, but I WILL be looking into this. The other devices connecting fine are Sidekick 4G, Wife's Nexus S, Acer Aspire one, HP tx2000 laptop, and my wife's HP laptop. I also have my satellite receiver connected via ethernet.

THIS FIXED IT! I tried it first since it was the simplest solution and I've been 4 days with no loss of connectivity since I changed it to AES only, which all my clients do support! Thanks so much!

G2 Verizon - Wifi Won't Connect

Has anyone had any issues connecting to Wifi networks on their G2s? I got the verizon version on Saturday and haven't been able to get the phone working on 2 different wifi networks. I can connect to the wifi network just fine, but I can't access the internet at all. I can confirm that other devices are able to connect no problem.
Curious if anyone has some thoughts on how to potentially fix this. If not, will be heading back to Verizon to get a new one. Thanks in advance for the help.

I have the AT&T G2 version , it will connect to any wireless router but the connection will last 5 seconds then no internet, this is totally unacceptable I upgraded from the G-Pro and may go back as that never had this issue, I did read LG had a similar problem with the Nexus 4 and Optimus G

Mine works fine. I have a VZW G2 and an ATT G2 connected on the same router. It connects to both G and N networks.

No issues with my Verizon G2.

Did you try rebooting your router? I see this at home with the families iOS devices a lot, especially after heavy data traffic. I'll turn off the router for a couple hours or overnight and the next day all is well. Router is open, no encryption.

I have the exact same problem. It will sometimes transfer some data using browsers, but nothing on facebook, pandora, or the play store it will say connection lost or not data connection.
My wife has the same phone and it works no problem and also the laptop. Must be a dud wifi radio or something like that. Mine is going back to the store tomorrow.

Are you trying to use adblock by any chance? I was and it was causing the same issue you have. I uninstalled it and changed my proxy settings back to none and wifi is working great now.

Just received my LG G2 White brand new from T-Mobile about 2 hours ago. After many attempts to troubleshoot the issue it all failed. The problem is Wifi will connect to router and even work but after 30 seconds the connection goes down. The actual Wifi signal shows connected but no internet it gets stock. We tried resetting the phone and toggling with different features but still it did the same thing. T-Mobile is the worst they were trying to have me ship the phone back and leave me phone less for days. I complained and they are sending another one overnight but have charged me for the phone on my account. Mind you I've had months of bad service, after all I think I got a defective phone. I've read some other people having the same issue with other carriers. If I get another one with the same issue I'm jumping boat. If anyone knows of a work around let me know. I tried 2 different routers same issues connects then it randomly disconnects and stops downloading or transferring data.
Reset Phone - didn't work
Turned off mobile data - didn't work
Turned off wifi sleep - didn't work

I'm on Verizon. I have trouble with initial connection to wi-fi. It says obtaining IP address for a very long time. Even if I have a very strong signal. It takes about five minutes. It eventually connects and works fine. Then next time I try to connect to that router it works fine. It's only the first time I try to connect to a new router.

I just got this phone over the weekend and I was also having trouble connecting to my home wifi.
It would stay connected for 30 seconds or a couple of minutes then disconnect however the entire time the status under the Wi-Fi settings page says Connected even though I couldn't access the internet or the admin page of the router. Frustrating. If I turned off the mobile data, the wifi, the phone, the router, or some other unknown combination of events it would then reconnect again for another 30 seconds to a couple of minutes.
I called Verizon, they told me to take the phone back since I was within my 14 days. I did this and was optimistic. Then the new phone immediately experienced the same issue.
I did some more research, changed my router from 20 mhz channel width to auto 20/40 mhz. Not sure why it was set to just 20. I thought that would fix it. Nope.
I tried to set my phone to use a static IP, that didn't work either.
Then last night I tried the WPS Push Button option instead of using a password. This method worked and my phone stayed connected. I haven't had a chance to repeat my steps to verify it works again but wondering how other people are connecting, password, wps push button, wps pin? WPS is not my preferred option due to the security risks but just trying to track down what works and what doesn't.
I am able to connect at work just fine using a password.

I'm having a similar problem - my work network has no problem connecting while my home network almost never works with this phone (~25% of the time, other devices have no problem). Occasionally, resetting the phone or just turning on-and-off WiFi fixes the problem, but more often I just give up and use 4G. Anyway, if anyone finds a solution, please post! This is such a standard feature that should really work out of the box.
In case it helps, my home network uses "WPA/WPA2 PSK" security and my work connects to "802.1x EAP" security - also I'm not adverse to changing the security options if it fixes the problem.
Thanks! Nick

After reading more on this, I've decided this issue is router related not phone related.
I discovered my router reached end of life in April of this year is no longer receiving firmware updates. Newer versions of my router have received multiple updates since then.
I will be buying a new router. I report back on if it works.

I really don't think it is "router related" as all my other devices work as expected with my router. A new router may fix the problem, but I'm pretty sure the phone's WiFi is buggy and not the router..

In my situation it really appears to be how my router is handling the connection when I connect with a password since I can connect with limited security.
Does your router have a firmware update available for it? If so, have you applied it?

Received my new to me router yesterday with updated firmware as of 10/7/13.
My phone was connected for a few hours last night and I have not had any problems today. I'll report back if I start experiencing any issues but getting rid of my old, end of life router and replacing it with a newer router worked for me.
I did not buy a brand new router either. I went with a cradlepoint mbr95 which has been on the market for awhile and has already had a few firmware updates.

Check you wireless security settings
Had a similar issue to this and it seemingly was resolved when I moved the wireless router security over from WPA/WPA2 personal to WPA2 personal only. The phone found the WAP and connected right away. I tried to reproduce the behavior but alas I have not been able to do so. Perhaps this will help others.

hi guys
i found the problem
it happens just when you disable auto update in "settings>general>about phone>update center>software update>check automatically"

[Q] My Nexus 4 conect in Wi-Fi but don't access web

Guys, recently bought a Nexus 4 and it normally connects via wifi but can not connect.
I was using the Android 4.2.2 OTA updated to Android 4.3 and the problem persists.
The Nexus 4 connects normally, but the icons of wifi connection and carrier signal are gray instead of blue and even trying to install applications via Google Play or simply access a site via browser do not work and accuse the connection fails.
I was tested and the router's signal is good and other equipment that I usually work (other Android smartphones and notebook).
My router is standard G and I use WPA2.

Oddly enough, I have the Nexus just 3 days and only had access to the router so far from home, but today I'll look for a router to test the public.
But either way it's frustrating the Nexus 4 have these compatibility issues when connecting to a wifi router.
Before making the switch router, is it not possible to find out which configuration of WLAN could cause this? Does Google do not have this documented?

i feel your pain, been there
it could be your router, from the way it assigns ip addresses to your type of encryption. by any chance is it a linksys G router? that was my problem before until i just decided to get an N router.
did you try switching to WEP or open to see if the problem persists? or changing your gateway ip address? or changing which ch your wifi is on?
never hurts to try

Should factory reset your router and upgrade firmware first, then immediately connect to it without encryption and see if it work.

Wifi issue related to root?

Hi Folks,
I have been postponing this post but nothing ive seemed to do has worked. I THINK after i rooted my issues started. I am unable to browse the net or anything when connected to my wifi. I have reset the router, forgotten and rejoined the network with no avail. All my other devices do not have this issue. Im not really sure what else to say so maybe some of you gurus could pick my brain. Though this is a wifi only issue and on this network. When connected to other networks im fine. My setup is as follows. I have a hard line going from the router the ISP provided in the other end of the house to the router in my room. Like i said my phone is the only device that has issues on this network.
thanks in advance.

That's a pretty strange issue, not sure there is going to be much help... I've had some strange, random issues with my S5. I had issues with wireless, xposed and some other apps after rooting the first time. I got tired of it and used Odin to reflash the stock firmware, then performed a factory reset and rooted afterwords. I haven't had any problems at all after doing this... In all honesty, that's the route I would go if I were you. Sorry I couldn't be more helpful, hope you get sorted out

Just wanted to agree with BadKarma on this. I've not had your exact issue, but I have had some similar stuff after rooting originally. I used Odin to go back to stock and rooted again and have been no issues since. Hope it works out. . .

well i used odin and got back but it turns out it seems to be the router? im on stock with no root and still cant access the net or anything else when im connected to the router. any thoughts on this?

Can you reset the settings in the router via your pc?

Try connecting standing right next to the router. I had this issue with my Note 2 and it ended up being a physical issue with the wireless chip or antennas. It's actually the reason I'm not on a S5.

Not that u want to hear this, but I had to replace my router for the same reason. My router would only pick up certain devices, had to do with hardware and firewall security settings.

Ok so i changed to security in my router to aes and tkip and i was able to connect and browse the net and so forth. but i just got home and connected and wasnt able to get access to the net again. i tried forgetting network and re-entering it with no luck.

First and foremost you have to isolate the issue to either ur phone or the router. In order to do that its very simple.... can you connect to wifi outside of your house like starbucks or friends wfii? If the answer is yes than the issue lies solely with your router. Let me know what you find out and I can help guide you <---- systems administrator Also please provide the make and model of your router as well as your modem and your ISP.
EDIT: I just read the line where you talk about having another router in your room. I can already tell you this is probably NOT an issue with your phone but rather your setup. The secondary router must be setup as a repeater or bridge OR on a different subnet. This gets very tricky for average home user and I do not recommend you tackle it on your own. Also your main router has to be able to play nice with the secondary and if it's one provided by your ISP it's probably a POS. Also your phone is probably not the only device having issues with this setup.... its the only one you are noticing having issues. Android OS is very sensitive to weird wifi setups and anything out of the norm will set it off. It's actually a great tool in diagnosing wifi issues.

Hi there thanks for the reply. Yes i can connect to any other router without issue. The router is my Router Info:
Name N300 Wireless Router
Model F9K1002v5 (01B)
Firmware 5.00.15(Nov 1 2013)
Serial No. 12349GC2508237
Boot Loader 0.12
I use my tablet and other pcs within this wifi. It is under a different subnet as well. (i think so been a while since ive done any networking) The main router that comes in has the standard IP 192.168.1.1 and the IP for my router in my room (basically set up like this since my room is quite far and gets bad signal from the main router, Cable in -> Main Router -> Hardwire hooked into a port -> ethernet run to my room -> Connected to a port on the wireless router) 192.168.2.1. My ISP is Optimumn Online. My wifi was working fine until about 10 mins ago. seems to happen so often. I did change the security a while back to TKIP + AES on the router and made sure it was the same on the phone and it was working fine for days until like i said about 10 mins ago.

This leads me to think that perhaps the router (however old or new) may have a setting, or an actual limit, on how many devices connect to it.
If not that, perhaps if you rooted, and tried removing bloat, you may have been a bit overzealous and removed something related to WiFi and are now having this issue as a result.
I have only removed the list of apps and bloat that have been posted on Ricks Rom HERE. The ONLY problem I have seen since removing this list, was that I can no longer access PhotoVault correctly. Gives me an error saying that it has no connection to the database, but my 4G is working fine at the time as I was downloading via steam and streaming a movie, and playing a PC game at the same time...

You have the right setup with a different subnet. It's possible the main router is assigning the same IP address that your router has to another device. It would be best if you picked up another router that has repeater capabilities and set it up in repeater mode. Also reserve an IP address for your router from the main router to avoid IP conflicts.
Another possibility is simply the wifi on your router is deteriorating and it's time for a replacement. I recommend the Netgear Nighthawk R7000 if you don't mind spending the $$$. If your on a bit of a budget the Netgear N900 (WNDR4500v2) is the next best thing that supports repeater mode.

well its been still working intermediary. I have to unplug the router and plug it back in then i can browse the net on my phone. idk if id like to lay out that kind of money for a new router. there has to be something else thats causing it. i set the router to reboot everyday, also my phone. its odd though. sometimes it works sometimes it dosent.

Wifi stays connected but loses internet access

After the upgrade to Lollipop on my Yoga 2 830, I'm noticing that the wifi gets no internet access even while connected every so often. I have to turn off and turn back on the wifi for it to reconnect. Is anyone else having this issue? I don't have any issues w/ any of my other devices connected to wifi.
I'm not on static IP, no issues with the router. I didn't have any issues on kitkat. Please share if you also have this issue. Thanks.

Hello!
Did you try connecting your device to another wifi network to see if the problem persists?
I have noticed something similar happening with my Xperia Z ultra after it upgraded to lollipop. I realised that it was happening only on the older wifi routers (I use an ancient Linksys WRT54G), but seems to have no problem with the newer ones.
Changing the channel of your wifi router might help alleviate the problem. I am not certain if it would work in your case, but if you do not have another router handy, this just might do the trick. If you are looking to change the channel, an easy guide is available here.
I hope this helps

I've got a Netgear AC1900 nighthawk with a netgear ex6200 range extender. The tablet is primarily connected to the 5ghz band on the nighthawk. I do have other routers but they are older. I might have to try to take it to work and see if I lose internet access.
I've changed the bands around and it does help. I've rebooted the router, rebooted the tablet, forgotten the wifi and so on. It's still happening after some time. By the looks of it, there are others that have experienced this on other devices. I haven't done a factory reset. I would prefer not have to go through the setup again.
